Enhancing Your XRF Sample Preparation

In addition to our high-purity Spectromelt® fusion fluxes, we offer a number of additives that can greatly enhance and simplify your XRF sample preparation.

Using fusion additives from MilliporeSigma, you benefit in a number of ways. Non-wetting additives like lithium bromide and potassium iodide, for example, act as releasing agents that help to prevent the borate glasses from sticking to the platinum ware. This makes it easier to remove the sample after fusion and protects your equipment. When your sample contains certain substances that might react with your XRF mold, such as metals or sulfides, oxidizers like lithium nitrate or sodium nitrate make sure that the sample is fully oxidized before flux melting or during fusion in order to avoid damage to your expensive platinum ware. Heavy absorbers, e.g. lanthanum oxide, minimize matrix effects and increase spectrometer selectivity.

Our broad portfolio consists of multiplex panels that allow you to choose, within the panel, analytes that best meet your needs. On a separate tab you can choose the premixed cytokine format or a single plex kit.

Cell Signaling Kits & MAPmates™

Choose fixed kits that allow you to explore entire pathways or processes. Or design your own kits by choosing single plex MAPmates™, following the provided guidelines.

The following MAPmates™ should not be plexed together:
-MAPmates™ that require a different assay buffer
-Phospho-specific and total MAPmate™ pairs, e.g. total GSK3β and GSK3β (Ser 9)
-PanTyr and site-specific MAPmates™, e.g. Phospho-EGF Receptor and phospho-STAT1 (Tyr701)
-More than 1 phospho-MAPmate™ for a single target (Akt, STAT3)
-GAPDH and β-Tubulin cannot be plexed with kits or MAPmates™ containing panTyr
